Before you start

Before beginning the cooking process, organize all ingredients and tools to ensure a smooth workflow. Slice the beef into thin, even portions and pound them if necessary.

Clean and thinly slice the mushrooms, and shred or slice the mozzarella cheese. Have the steak seasoning, pan gravy, and prepared side dishes ready. Ensure the skillet is clean and ready, and have a plate and toothpicks nearby.

Instructions

Assembling and Seasoning the Beef Rolls

  1. Season and Assemble the Beef Rolls
    Lay the thin beef steak slices flat on a clean cutting board. Season both sides evenly with the steak seasoning. Place a portion of sliced mushrooms and mozzarella cheese near one end of each steak slice. Roll the beef tightly around the filling, tucking in the sides to secure the cheese, and fasten the seam with toothpicks.
    Look for The rolls should be compact and tightly sealed.
    Tip Do not overfill the beef rolls to prevent the cheese from leaking.

The beef slices should be tightly rolled around the mushroom and mozzarella filling, secured firmly with toothpicks, and evenly seasoned on all sides with steak seasoning. The rolls should feel compact and ready for searing, with no cheese spilling out prematurely.

Searing the Beef Rolls

  1. Sear the Beef Rolls
    Heat a large skillet over medium-high heat. Carefully place the beef rolls in the hot skillet, seam-side down. Sear for two to three minutes per side, turning with tongs, until a deep golden-brown crust forms on all surfaces.
    Look for A rich brown crust should form on the beef.
    Tip Searing the seam side first helps lock the roll shape.

The beef rolls should have a deep brown, caramelized crust on all sides after searing in the hot skillet. The skillet should have a layer of browned bits stuck to the bottom, which will be lifted and incorporated when the pan gravy is added in the next step.

Simmering in Rich Pan Gravy

  1. Simmer in Pan Gravy
    Pour the rich pan gravy into the skillet with the beef rolls. Simmer, covered, for five to seven minutes until the steak reaches an internal temperature of 145°F (63°C). Remove from heat and let the meat rest for at least 3 minutes to allow the juices to redistribute and the mozzarella to melt completely.
    Look for The gravy should be hot and bubbling gently.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Always verify the temperature with a meat thermometer.
  2. Plate and Serve
    Transfer the warm mashed potatoes, roasted carrots, and green beans to serving plates. Arrange the juicy beef rolls alongside the vegetables, spooning the warm pan gravy over the top before serving.
    Look for The dish should be beautifully arranged and piping hot.
    Tip Remove the toothpicks carefully before plating.

The gravy should be hot, bubbling gently, and clinging to the beef rolls. The beef rolls should be tender, and when sliced, the mozzarella cheese inside should be completely melted and gooey. The internal temperature of the beef must reach 145 degrees Fahrenheit before resting.

Common mistakes

One common mistake is overfilling the beef rolls, which makes them difficult to secure and causes the cheese to leak out entirely during searing.

Another error is not heating the skillet sufficiently before adding the beef rolls; a cold pan will steam the meat instead of searing it, resulting in a gray exterior without the desired caramelized crust.

Lastly, failing to remove the toothpicks before serving can be a safety hazard, so always keep track of how many toothpicks are used in each roll.

How to tell it’s done

The beef rolls are perfectly cooked when the steak is tender and the cheese inside is fully melted and gooey. To ensure food safety, insert an instant-read thermometer into the thickest part of the beef roll, avoiding the cheese filling if possible.

The internal temperature of the whole cut meat must reach at least 145°F (63°C). Once this temperature is reached, remove the rolls from the heat and let them rest for at least 3 minutes to allow the juices to redistribute.
